Spring RequestMapping读取编码＆amp;

Question

我正在尝试获取RequestMapping来获取以下url路径名。

action?param1=6&param2=b&param3=true&param4=50652&param5=2

我能够让下面的路径发挥作用。然而，当转换＆amp;到'＆amp;放大器;”我无法读取任何参数。

action?param1=6&param2=b&param3=true&param4=50652&param5=2

行动方法

@RequestMapping(value = "/action", method = RequestMethod.GET)
public ModelAndView doAction(HttpServletRequest httpRequest, HttpServletResponse httpResponse)
        throws Exception {
log.info(httpRequest.getParameter("param1"));
}

FYI 我想避开任何字符串操作
